I made my first errand trip on public transport with my Cafe Bag and it's a dream. Because time was of the essence, the trip was really long, the weather really hot and the fare machines not cooperative, finding my stuff fast, making sure I got the right connection I needed efficient organization

That back pocket is really really handy to slip in timetables and maps and putting my documents in and out of the main pocket was a snap.

I also used it on slow walk in a park where time was of no concern but making my load feel lighter was essential. To that effect, I used the waist strap to lighten the load on my shoulder.
It worked so well, I almost forgot I had the Cafe Bag on. A first in many many years of wearing purses of any shape, size and material.
